[GRASS-user] problem inporting large datasets with v.in.ascii

[Michael Perdue]

Jeroen,

if you're working with with point data then you can use the -b switch  
so that grass doesn't build topology. However, as far as I'm aware,  
v.surf.rst is the only other module that will work without topology  
so you might want to consider breaking your data up into smaller chunks.

Cheers,

Mike
